I've considered taking up this 21 technique. Now then, i've been told not to perform this every time you work out your biceps, so should I work them out every 2-3 weeks or so? And during the weeks i'm not using 21's, should I peform regular workouts such as curls and such?

Okay, so i've planed this.Week one - Lots of reps with a lower weight for four setsWeek two - Lower reps of higher weight for four setsWeek three - 21's or supersets, which everyone I fancy at the time for three sets.That alright?
